CARPET LINER.

Application med march 2, 1928.' serial No. 822,274.

To aZZ whom it may concern-x- Be it known that I, BERGET HENRI BnooK- soM, a citizen of the United States, residing at Michigan City, in the county of L'aporte and State of Indiana, have inven'ted a new and useful Improvement in Carpet Liners, of which the following is a specification.

My invention relates to an improved form of l1ner or pad for use under carpets to cushion the same and for other uses in which it is desirable to, employ a resilient pad.

'My invention consists essentially of av layer of intertwined resilient fibers having preferably a considerable degree of elastic action such that the sheet of material tends to resume and mainta'in its original thickness after being compressed and I find for this purpose that a p'ad or layer of curled animal hair serves admirably. I have found that the pad of resilient fibers is not substantial enough for all purposes, such as carpet liners, unless protected vin some manner and my invention more specifically consists in providing the layer of resilient material wlth a layer of hacking material on' one or both of its faces, said hacking material being preferably fibrous and loosely' woven and having its threads or fibers at intervals extending through the sheet of resilient material, the loops of the threads or fibers extending through the resilient material tending to hold the hacking layer or layers and resilient material together, thus facilitating handling the liner or resilient pad and preventing undue disintegration during shipment and use. In cases where both sides of the curled hair pad are protected with layers of fibrous material such for example as burlap, the threads of the burlap are readily forced throu h the curled i hair pad and also through the ayer of bur-.

lap on the other side of the pad leaving projecting loops that have the efi'ect of interlooking` the body portion of the pad and the protecting layers on its surfaces. be understood that the loops referred to may be forced through the pad from one or'both of the sired.

My invention will best be understood by protecting layers of burlap' as dereference to the accompanying drawings ss l showing a preferred embodiment thereof in which v Fig. is a tranverse 'sectional view It will through a part of a pad having a protective layer on one of its surfaces, y

Fig.2 shows in a view similar to Fig. 1, a pad provided With a protective layer on both of its surfaces, and

Fig. 3 is a detail view of a form of needlev that may be employed to force the threads of the protective material through the pad.

Similar numerals refer to similar parts throughout the several views.

As shown in Fig. 1, the sheet oflresilient material, preferably curled animal hair, is indicated at 10 and on one of its surfaces a protective layer 11 is shown consisting p'referably of coarse fabric, such as burlap. At 11a a loop of the thread'or fabric of the layer of material 11 is indicated as having been forced through the Sheet of material 10 and forced through the sheet of material 10.1

It' will be understood that loops 11b are `formed in the manner described over the entire surface of the Sheet material 10, the spa-(ring of the loops being such as to. hold the sheet of'material 10 and the protective layer 11 securely together so that the sheet of material 10 is materially reinforced by the layer 11.

As shown in Fig. 2 the sheet of resilient.

material 10 is provided with a first protective layer, preferabhy' of fabric such as burlap, as described in connection with Fig. 1 and also on its other surface with a second similar layer of protective material 13 and. in this case the loops 11h formed as described in connection with Fig. 1 extend through the second protective layer 13 and similar loops 13h, 13b are shown as formed from the laver 13 and extending through thesheet of. material 10 and also through 'the protective layer 11. This construction has the advantages over 'that shown in Fig. 1, of protecting both sides of the resilient material `10 and furthermore the vinterlocking of the' loops refer-red 'to is more positive than it i's with the construction shown in Fig. 1, for the reason that each loop extends through and interlocks with the fabric of the other protective layer of ma-j terial. In. this case as in the construction, shown in Fig'. 1- the loops may be given any reo desired spacing over the entire surface of the pad so that the protective layers are held securely to the body portion of the pad as may be required for any particular purpose to which'the pad is put. I find that resilient pads constructed as described are very effective for use as carpet liners, that is for laying on a floor under a carpet or rug since the resilient nature of the body portion of the pad gives an easy and pleasing effect when walking on the carpet, the material does not easily mat, but on the other hand tends to) maintain its original shape and furthermore the protective layer or. layers of material secured to the resilient material, protects the resilient material from disintegration which Would otherwise quickly occur from repeatedly walking on the rug. It will further be observed that the resilient padsconstructed as described are quite' substantial in nature and .may readily be made in any desired lengths and widths and may readily be formed in rolls for purposes of shipping, without danger of damage to the pads.

As shown in Fig. 3 the needle 12 may be of any desired conformation as long as it is provided with a hook 12a projecting vfrom the body portion of the needle sufliciently to engage and carr withit one of the threads 11a of the fabric used as a protective layer. rl`he needle ma be operated 'by any convenient means, w ether manually or by suitable machinery and its operation in forming any one of the loops re- 'ferred to is to engage a thread of the fabric of the protecting layer as the needle is beingr forced through the pad and carr ing the thread through the opposite side o the pad, thus forming a loop ofthe kind referred to above, projecting from the surface of the pad opposite to that o'n which the protectiye layer from which the thread is drawn, is disposed. The loo is retained in the position indicated in t e drawings upon withdrawal of the needle, b the engagement of the thread or fiber o the loop with the material of the sheet 10 and also Where two protective layers of material are employed, by engagement with the threads or fibers' of the layer of protective material on 'the side-of the pad adjacent the loop.

.In this manner the loops are interlocked with the resilient material of the Sheet 10 and also Where two protective layers are employed, with the threads or fibers of the other protective layer.

In manufacturing resilient pads as above described, where the layer of resilient fiber is relatively thick, or the threads of the protective .fabric are relatively non-yieldmg, the forminp'` of the loo s described from the threads of the protectlve fabric may break these threads or stretch these threads by displacing the .fibers of the threads longitudinally thereof relatively to each other, without however, detracting materially from the value of the finished pads, since the interlocking action of the loops is quite as effective for thel purposes above described as though the threads remained unbroken or unstretched; in other cases, where the layers of resilient fiber are comparatively thin and Where the protective fabric consists of loosely twisted threads as found in burlap, the loops may be formed as above described without breaking the threads and without materially changing their original form.

While I have shown m invention in the particular embodiment a ove described, it

'-will be understood that I do-not limit my-t self to this exact construction as I may employ equivalents known to'the art at the time of the filing of this application without departing from the scope of the appended claims.
